WEATHER-STRIP.

Application filed December 2, 1912.

To all whom it may concern:

Be it known that JOHN F. STEVENSON, a citizen of the United States ofAmerica, and resident of Tower Hill, county of Hamilton, and State ofOhio, has invented certain new and useful Improvements inWVeather-Strips, of which the following is a specification.

This invention relates to weather strips and particularly to stripswhich are capable of being moved to operative positions, when the doorsor windows to which they are secured are moved to closed positions.

An object of this invention is to produce an improved weather strip forswinging doors or windows, which is capable of producing a weather-tightjoint between the door or window and its stationary or supporting frame.This and other objects-.1 attain by means of a strip embodying thefeatures herein described, and illustrated in the drawings accompanyingand forming apart of this application.

In thedrawings Figure 1 is a fragmental vertical sectional view of adoor and door sill, and illustrates an embodiment of my invention movedto the sill-engaging position. Fig. 2 is a view corresponding to Fig.

'1, except that the door is not in the closed position'and the stripshown as an embodi-.

ment of my invention is moved to a position out of engagement with thestationary sill.

Fig. 3 isv a fragmental vertical elevation of a swinging window equippedwith a strip embodying my invention, the window being shown in theclosed position, relatively to its stationary supporting frame. Fig.4 isa view corresponding to Fig. 3 and illustratesthe window swung to apartially open position, relatively to the stationary supporting frame,and the weather strip moved to a position in which it clears the frame.

The illustrated embodiment of my invention consists of. ahinged strip 5,which is .mounted on the outside of a swingingdoor or window sash, andis adapted to move across and tow engage a vertical face .of the sill ora corresponding stationary member,

when the door or window, to which it is secured, is moved to the closedposition.

' In Figs. 1 and 2 I have shown an embodiment of my invention which isparticularly adapted to be employed on aswinging door, and asillustrated, includes a Z-bar 6, which is secured to'the outside. of thedoor near its lower edge, and the weather strip 5, which Specificationof Letters Patent.

is mounted 'on the Z-bar by means of a hinge 7, and is capable of beingmoved when the door is closedfro1n' a substantially horizontal position,as shown in Fig. 2, to a substantially vertical position, as shown inFig. 1, in which it engages a vertical face of'a stationary member 8,across which it moves during the operation of closing the door. In Figs.1 and '2, the stationary member referred to,-is, the door sill and theweather strip is so constructed that it moves into engagement with .theouter vertical face of the sill when the door is closed. The strip 5, asillustrated, consists of a channel iron and it is actuated by means ofashiftable member 9,.through the agency of alink 1 0'and a bolt 11,.whichis provided with an arc-shaped head. The member 9, as illustratedzinFigs. .1 and 2, ismountedin a way or guide 12, whichi'symounted on thedoor .13 and is. located at or near its lower edge. One end of themember 9 is pivotally secured to the link 10 and the other end isprovided with a down-turned head or pro 1ect1on 14, which is adapted toengage the inner yertieal face of the sill 8', during the operation ofclosing the door and which operates to move the member 9 inwardly,relatively to thedoor, and to thereby swing the strip 5 from ahorizontal to a vertical position, in which, as has been said, itengages the sill. The member 91 and the link 10 are so constructedandlocated with reference to the strip 5, that the strip 5 assumes thevertical position and engages the sill when the. door 13 is moved to thefully A spring 15 isprovided for actuating the. member. 9 to move thestrip 5 to the horizontal position. As illustrated, a coil spring isemployedyand it is located between a shoulder formed on the member 9 andthe inner end of the guide 12. The lower end of the. guide isslotted, sothat the head 14 moves, in response to the pressure of thespring, to aposition interwhen the door is open and is not conspicuous enough to beunsightly when the'door is closed. The zbar 6, as illustrated, extendstransversely across and parallel to the lower edgeof'the door on.whichit is mounted,

and it is so located that its projectingiflange extends downwardly andthe channel iron or strip 5 is secured to the downwardly projectingflange by means of the hinge 7. The strip or channel 5 is turned so thatits flanges project downwardly when the strip is in the horizontalposition and inwardly when it is in the vertical position, and it is somounted that the outer end of the channel travels through a relativelylong path and is lifted a relatively large amount during the operationof turning the channel from the vertical to the horizontal position.This is accomplished by so locating the hinge, relatively to the strip,that the pivotal point of the strip is located nearer the upper or inneredge than the lower or outer edge of the strip. The bolt 11, to whichthe link 10 is secured, is so located, relatively to the pivotal pointofv the hinge, that thelower edge of the hinge will be swung upwardly toa position clear of the top face of the sill for a slight openingmovement of the door or a slight movement of the member 9. The roundedhead of the bolt is also so formed that it will aid the member 14 inmoving or holding the strip 5 in the horizontal position during theoperation of opening the door. This is accomplished by so proportioningthe bolt that its rounded or arc-shaped head will engage and ride acrossthe sill during the operation of opening the door, if the member 9 hasfor any reason failed to move the strip 5 to its horizontal position.During the operation of closing the door, the strip 5 is held in thehorizontal position, by the spring 15, until after the head 14 engagesthe inner vertical face of the sill, and the outer edge of the stripmoves clear across the top of the sill before the strip is turned fromthe horizontal position. When the door is almost closed the head 14engages the sill and is moved from the position shown in Fig. 2 to theposition shown in Fig. 1, by the further closing of the door, and whenthe door is fully closed, it operates through the agency of the link andthe bolt 11 to hold the lower or outer flange of the strip or channeliron 5 in contact with the outer vertical face of the sill. This forms asubstantially weather-tight joint and absolutely prevents water fromrunning-down the outer surface-of the door and through the crack betweenthe door and the sill. In opening the door, the head 14 of the member 9is released from the sill and the spring 15 shifts the member 9outwardly, relatively to the door, and swings the strip to thehorizontal position, in which it clears the sill. In Figs. 8 and 4 Ihave shownan embodi- 'ment of my invention. which may be employed withan inwardly swinging French window 16. The strip 5 is similar to thestripillustrated in Figs. 1 and 2 and it is mounted by means of a hinge7 on a Z-bar 6,

the projecting flange of which is turned downwardly. The Z'bar extendstransversely across the window sash and is lo cated near its lower end.The actuating member of the strip consists of a hollow tubular member17, which is located within and is movable longitudinally along asleeveo'r way 18, which projects through a transversely extendingaperture provided near the lower edge of the sash of the window. A coilspring 19 is located between an abutment, provided at the inner end ofthe sleeve 18, and the head portion of the tubular member 17, and isadapted to move the member 17 to the position shown in Fig. 4, in whichit holds the strip, 5 in a horizontal position, through the agency ofthe link 10 and the bolt 11. In Figs. 3 and 4, an angle iron 21 ismounted on the window sill and forms an abutment against which thewindow sash contacts when the window is in the closed position. Asillustrated, the projecting flange of the angle iron 21 extends upwardlybeyond the lower edge of the sash and is provided in its upper edge witha notch 22. The sleeve 18, and consequently, the tubular member 17,areso located on the window sash that the outer end of the tubularmember engages the projecting flange of the angle iron 21 at a pointimmediately adjacent to the notch 22, during the operation of closingthe window and the notch receives the link lOwhen the window is closedand the strip 5 is in the vertical position. When the strip is in thisposition the rounded head of the bolt 11 is located onthe outside of theprojecting flange of the iron 21 in such a position that it will aid thetubular member 17 in swinging the strip from the vertical to thehorizontal position, by riding over the upper edge of the flange duringthe operation of opening the window. The spring 19, however, normallytends to hold the tubular member 17 in the projecting...

position, shown in Fig.4 and consequently tends to move the strip to thehorizontal position. During the window closing operation the headportion of the tubular member 7 contacts with the angle irons 21 and ismoved into the sleeve 18, in which position it compresses the spring19and holds .the strip 5 in a vertical position, with its lower flange inengagement with the outer .face of the upwardly projecting flange of.-

ing flange of the angle iron 21, corresponds .to the sill 8, in itscooperation with the strip. The hinges employed in mounting both of thestrips 5 may be located near the ends ofthe strips, and various meansmay be employed for mounting the stripsonthe doors or windows, withwhich they are employed. By employing the link 10 between the strip andits actuating member, a more substantial device is obtained than haspreviously been procured, and the construction of the strip and itsactuating mechanism ismaterially simplified and its operation isrendered more positive.

It will be understood that, while the strip is illustrated in Figs. 3and l, in the position for closing the joint between the lower edge ofthe window, that it may be employed with equal success for closing thejoints between the other edges of the sash and the window frame, andthat various changes, modifications and substitutions may be made in thedevice illustrated without departing from the spirit and scope of myinvention as set forth by the appended claim.

What I claim is:

In combination with a stationary abutment, a swinging member capable ofbeing moved to an open or a closed position, with relation to theabutment, a

weather strip hinged on said member, a shiftable member mounted withinthe swinging member and capable of being engaged by said abutment, alink pivotally se: cured to the shiftable member, a bolt having arounded head mounted on the shiftable member and to which said link ispivotally secured, said bolt being so mounted that its rounded headengages said abutment and aids in the movement of said strip to aposition clear of the abutment, and a spring located within the swingingmember and the shiftable member, for engaging the shiftable member andfor thereby swinging the strip to a position clear of the abutment. i

In testimony whereof, I have hereunto subscribed my name this 30th dayof November, 1912. 7
